EDWARD IV. BOWSLAUGH, OF GRIMSBY, ONTARIO, CANADA.

INSIDE WIN DOW BLIND.

SPECIFICATION forming To all whom it may concern-.-

Be it known that I, E. W. BOWSLAUGH, of Grimsby, in the Province ofOntario and Dominion of Canada, have invented certain new and usefulImprovements in Inside \Vindow- Blinds; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in inside windowblinds; and itconsists in attaching the slats together by means of webbing and hooks,which hooks are passed through the edges of the slats at one end andthrough the webbing at the other.

It still further consists in the arrangement and combination of parts,which will be more fully described hereinafter.

The object of my invention is to provide a blind made of slats withmeans for raising the slats all together, raising them at one end only,adjusting the slats in such a position that they will allow the light topass into the room, and to remove and replace the blind without havingto remove any of the screws from the hinges, thus adapting the blind tobe used in a good many difi'erent positions.

Figure 1 is afrontelevation of my invention complete. Fig.2 is an edgeview of the same, showing the slats in one position in solid lines andanother in dotted lines. Fig. 3 is an enlarged detail view, showing howthe webbing is attached to the slats by the hooks. Fig. 4 is aperspective of the two parts of the hinge separated from each other.

A represents a window-casing, to which the blind is attached by means ofthe two hinges B. These hinges, as shown inFig. 4, are made of the tworemovable parts, one of which is provided with the hook O at its upperedge, so as to catch over the part D of the upper portion of the hinge.By making the hinge in two separable parts which are to be hookedtogether, instead of being fastened together by a pintle in the usualmanner, the blind can be removed from the window-frame and restored A toplace without removing one of the screws The upper part of the hinge'from the hinges. has a screw-hole made through its upper end,

part of Letters Patent No. 252,833, dated January 24, 1862. Applicationfiled November 11, 1881. (No model.)

and just below this screw-hole is made a slot, D, through which thesecond screw is passed. This slot is made so this upper part of thehinge can be adjusted into position without having toremove any of thescrews. Unless this part is placed directly in line with the other part,which must be attached directly to the top slat of the blind, the blindwill not work as perfectly as it should.

Making the blind removable without having to displace any screws is agreatimprovement, because itenables every housekeeper to remove theblinds at will for the purpose of dusting and cleaning them.

The slats F are secured to the webbing G by means of the hooks H. Thesebooks are made of a single thickness of wire, and have their inner endspassed through the holes I made in the edges of the slats, and theirouter ends then passed through the webbing and bent downward, so as toprevent the webbing from slipping ofl from them.

Should it be desired at any time to remove any of the slats for anypurpose, the hook can be readily withdrawn from the hole at the edge ofthe slat, and as readily replaced.

The hinges are applied to the upper slat of the blind, sothat the jointcomes just over the inner edge of the slat, and thus when the slat isleft free to hang it inclines downward, so as to cause the blind to shutthe light out from the room to a very great degree.

Passed through the front edge of the top slat is any suitable hook orfastening device, L, and fastened to the window-casing just above it isanother guide, screw-eye, or hook, N, and toward one of the corners ofthe window-casing is secured another book, guide, or screw-eye, O. Thecord operating the slats is fastened to the hook, catch, or otherfastening secured to the top slat, and is then passed outward throughthe two screw-eyes, which form guides for it, and thence passes downalong the edge of the slats. By pulling upon this cord all of the slatsare raised horizontally, so as to allow the light to pass freely intothe room. If drawn up pasta horizontal position, the slats can be closedto any desired degree, and will deflect the lightwhich is passing intothe room up toward the ceiling; also, secured to the under side of thetop slat are the two screw eyes Q, through which the two cords R arepassed, and then from these screw-eyes they are passed down through theslots in the slats in the usual manner and fastened to the lower slat.By pulling upon one of these cords the slats can be raised at one endonly, so as to form a fan shape, or by pulling upon both of the cordstogether the slats will be raised up against the outer slat, leaving thewindow clear.

Having thus described my invention, I claim- 1. In combination with aninside blind, the hinge B, made in two parts, one of which is providedwith the hook U and the other with the portion D, over which the hookcatches, whereby the blind can be removed from the window without havingto remove the screws from the hinges, substantially as shown.

2. In combination with an inside blind, the hinges B, provided with thehooks G and parts D, the parts of the hinges being provided with slotsfor the screws to pass through, whereby can be detached without removingone of the screws, one of the parts being provided with a slot, so thatit can be adjusted in position, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD WATSON BOWSLAUGH.
